LOCOMOTIVE CONSTRUCTION.

Application filed April- 7, 1924. Serial No. 704,866.

To all whom it may concern:

Be it known that I, AUGUSTINE R. AYERS,

a citizen of the United States, residing at Cleveland, in the county of- Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Locomotive Constructions, of which the following is a specification.

This invention relates to steam locomotives and particularly to locomotives equipp ed with feed water heaters located on top of the. boiler either ahead or behind the stack.

-In constructions of this general character they are usually provided with pipes of comparatively large diameter extending upwardlyfronr the steam chests to the heater, one pipe being usually arranged on .each side of the smoke box. Because of the disposition of these pipes with respect to the remaining structure they obstruct the view of the engineman from the cab and furthermore make it extremely difficult to apply other pipes to the outside periphery of the smoke box without causing said latter pipes to project outwardly a considerable distance. Aside from obstructing the enginemens view these outwardly rojecting pipes make difficult the passage of persons back and forth on the running boards.

It is therefore the object of this invention to provide means whereby these pipes extending from the steam cheststo the heater may be so arranged as not to incur the above noted objections, this being rendered possible by providin recesses in the sides of the smoke box su ciently deep to permit the aforesaid pipes to be housed therein,-thus rendering the distance between the outsides' of these pipes substantially the same and in many instances less than the diameter of the smoke box. I

This construction offers the further possibility of effectually protecting the pipes from radiation as the arrangement permits of covering the pipes and also of disposlng them in closer proximity to the heat of the smoke box itself. In addition the recesses proved invention will be more apparent as;

this description proceeds, especially when considered in connection with the accompanying drawings wherein:

Figure 1 is a fragmentary front elevation of a steam locomotive constructed in accordance with my invention; 1

Fig. 2 is a fragmentary side elevation of the steam locomotive so constructed;

Fig. 3 is a fragmentary detail sectional view taken substantially on the plane indicated by line 33 of Fig. 2; and

Fig.4 is a similar view of a modified form of construction.

Referring now particularly to the drawings wherein like reference characters indicate like parts it will be noted that only suflicient of the locomotive is shown in order to illustrate the/ application of the invention, there being'shown in the drawings the steam chests 10, a feed water heater 11, a smoke box'12, stack 13 and running boards 14. In steam locomotive constructions of.

this character it is customary to provide upwardly extending pipes connecting the steam chests 10 with the heater 11. Heretofore these pipes have been arranged adjacent the outside of the smoke box and have therefore constituted objectionable obstructions both to the view of the enginemen and to the passage of persons along the running boards '14. l

In carrying out my invention I contemplate providing vertically arranged recesses in which these pipes may be disposed throughout the greater part of their length. These recesses may be produced in any one of a number of ways, for instance, as shown in Fig. 3 or Fig. 4 of the drawings. In Fig. 3 the wall 15 of the smoke box is shown as being cut away as at 16 to provide a vertically elongated opening therein. There is then attached to this opening a suitably shaped housing '17, this housing extending inwardly into the smoke box and being flanged as at 18 along its edges whereby it may be suitably riveted or welded to the wall 15 of the smoke box. I

There is thus produced on each side of the smoke box an open sided vertically extending recess, the diameter of which will be so selected as to freely receive the. pipe 19 which connects the steam chests 10 to the heater 11. The space around the pipe 19 will then be preferably filled with some form of lagging or pipe covering 20. The open side of the recess is. thereafter closed by means of a jacket or cover 21 whereby the original contour of the smoke box is restored and a smooth and sightly appearance roduced.

In ig. 4 a modified form of construction is illustrated and in this form of the invention it will be noted that the recess is produced by heating and forming the smoke box wall 15' in such a manner as to form a recess 22, the walls of which will be integral with the wall 15 of the smoke box. The jacket or cover 21 will then be. secured in place enclosing the recess and restoring the original contour of the smoke box. As in the preceding form the pipe 19 will preferably be covered with a pipe coverin of some charactor or the space within t e recess filled with lagging or other material 20.

With the above described structures there is realized the advantage of eliminating the obstructions arranged on the outer surface of the smoke box which are found objectionable for the reasons heretofore mentioned. In addition this construction offers the further possibility of effectually protecting the pipe from radiation and heat dissipation, the contents of the pipe being on the other hand maintained in closer proximity to the heat of the smoke box than was heretofore possible.

While it is possible with this arrangement to dispose the pipe 19 partially within the smoke box still the pipes are separated therefrom by the walls 17 or 22 and the character of the construction is such that no specially constructed fittings are necessary which in the case of leakage would prove disastrous to the steaming of'the engine.

While the principle of this invention has been described with reference to the pipes 19 extending from the steam chests to the heator still it will be immediately apparent that other of the pipes normally disposed on the outer surface of the boiler or smoke boxv together with a slightly modified form of the same have been illustrated herein in detail it should be understood that reservation is made to make such changes in the details of construction as may be deemed necessary and expedient and as may come within the purview of the accompanying claims.

Having thus described my invention, what I claim is:

1. A locomotive construction including a steam chest, a feed water heater, a smoke box and a pipe connecting said steam chest to said heater, said smoke box being formed with a recess adapted to receive said pipe.

2. In a steam locomotive structure of the character described including a steam chest, a feed water heater, a smoke box and a. pipe connecting said steam chest and feed water heater, said smoke box being provided with a recess adjacent one'side thereof adapted to house said pipe, and'a cover for closing theopen side of said recess.

3. In a steam locomotive construction including steam chests, a feed water heater, a smoke box and pipes connecting said steam chests to saidheater, vertically extending recesses formed in the sides of said smoke box adapted to receive said pipes, and covers for closing the open sides of said recesses.

4. In a steam locomotive structure of the character described including steam chests, a smoke box, a heater arranged on top of said smoke box and pipes extending upwardly from said steam chestsand connecting with said heater, the side Walls of said smoke box being provided with vertically extending passageways adapted" to receive said pipes, packing surrounding said pipes, and cover plates secured to said smoke box for closing the outer sides of said passageways.

5. In a locomotive construction, a plurality of steam chests, a smoke box, a feed water heater arranged on top of said smoke box, pipes extending upwardly from said steam chests to said heater, the walls of said smoke box being formed with vertically extending openings, housings secured to said smoke box along the edge of said openings and extending inwardly into said smoke box, said pipes extending through said housings, packing arranged in said'housing and surrounding said pipe, and cover plates secured to said smoke box and covering the openings in said smoke box.

6. A locomotive construction including a boiler, a smoke arch and pipes extending along said boiler and said smoke arch, said boiler or smoke arch being formed with recesses adapted to receive said pipes.

7 In a locomotive construction including a boiler, a smoke. box andpipesextending along the surface of said smoke box and boiler, said smoke box and boiler being provided with inwardly extending recesses adapted to enclose said pipes, and covers for closing the open sides of said recesses.

The foregoing specification signed at Cleveland, Ohio.
